T 0 all whom it may concern Be it known that I, GUs'rAr ORsrRoM, a subject of the King of Sweden, residing at Palsundsgatan 7, Stockholm, in the Kingdom of Sweden, have invented certain new and useful Improvements in Machines for Packing Cigarettes or- Similar Articles, of which the following is a specification.

This invention relates to a machine for packing cigarettes or similar articles in paper-bags, boxes or the like of that type in which the cigarettes are fed through one or more channels or the like into a portioning chamber or chute. According to the invention the set of cigarettes contained in the said chute is held separated from the cigarettes located in the said channel or channels by knives. After the said set has been pushed into the paper-bag, the bottom of the chute is raised in order to carry the cigarettes, entering the chute, while the said bottom is lowered, so that the cigarettes are successively lowered and always will have the proper position.

In the accompanying drawings Fig. 1 shows in a side view partially in section a cigarette packing machine arranged in accordance with this invention. Fig. 2 is a section on the line 22 in Fig. 1.

The invention is shown applied to a ma chine, in which the cigarettes 1 are located in a hopper 2 and fed from the same into two vertical channels 3 and 4, separated from one another by a partition wall 5, by two rotating drums 6 and 7 provided in their periphery with grooves 8. From each of the said drums 6 and 7 the cigarettes are caused to pass into the channels 3 and 4 respectively by parts 9, 11 and 12.

The partition wall 5 extends downwards into a portioning chamber or chute 22. The bottom 23 of the said chute is carried by a rod 24, the top end of which has a slot for the wall 5. The rod 24 is movable in suitable guides and is engaged by a lever arm 25, fixed to a shaft 26. A second arm 27 is fixed to the shaft 26 and, acted upon by a spring or the like, not shown, bears against a cam disk 28, provided on a rotating shaft 29. At the top of the chute 22 two knives 30 and 31 are provided, one at each side of the chute. The said knives are carried by arms 32 and 33 respectively, swing-ably mounted on shafts 34 and 35. Arms 32 and 33 are provided with toothed segments 36 and 37, engaging one another. A spring 38 fixed to an arm 39 and the frame of the machine tends to move the knives 30 and 31 toward one another. An arm 40 is connected with the arm 32 and bears against a cam disk 41 fixed on the shaft 29.

In Fig. 1 a portion of ten cigarettes is located in the chute 22, five on each side of the wall 5, and the knives 30, 31 are held in their inner position, sustaining the cigarettes located in the channels 3 and 4. The paperbags, adapted to receive the cigarettes, are located inpockets provided in a drum 42, which is rotated step by step. As one of the said pockets is opposite to the chute 22, the paper-bag 43 contained in the said partition is pushed by an arm or the like not shown upon a nozzle 44, connected with the chute. A plunger 45, actuated in any suitable manner, then pushes the said portion of cigarettes into the paper-bag and returns the latter into the pocket. After the end flaps of the bag a has been folded and pasted together, which is efi'ected during the continued rotary motion of the drum 42, the bag is moved from the pocket. These operations may be effected in any suitable manner.

After the cigarettes have been pushed from the chute 22 in the described manner, and the plunger 45 has been returned, the bottom 23 is raised'to the knives 30 and 31. The knives 30 are then withdrawn quickly by the cam disk 41, whereupon the cigarettes contained in the channels 3 and 4 fall down onto the bottom 23. The latter is then lowered slowly by the cam disk 28, so that the chute 22 is again filled with cigarettes. Owing to this arrangement the cigarettes will occupy the proper position in the chute and the cigarettes in the channels 3 and 4 are not deranged. The knives 30, 31 are then again moved inward to the position shown in Fig. 1, and the cigarettes contained in the chute are pushed into the subsequent bag.

The invention may, evidently, be modified in many respects without exceeding the limits of the invention.

I claim:

In a machine for packing cigarettes or similar articles in paper-bags, boxes or the like, the combination with a passage, through which the cigarettes are fed into a portioning chamber, and a shiftable member separating the cigarettes in the portioning chamher from the cigarettes located in the said passage, of a loose bottom in the said portioning chamber and means for moving the bottom to and from the inlet end of the chamber, in order that the bottom may sustain the cigarettes While they are charged into the said chamber.

In testimony whereof I have atfixed my signature in presence of tWo witnesses.
